SquirrelMail 1.4.23 SVN - Change_sqlpass plugins not working properly

Have anyone of you tried this plugins before? I am facing some issues after changing the password under the Options from the webmail it will not auto logged out nor redirect me back to the login page but instead giving me error message saying unable to verified page and click below to login page manually.

Is there any workaround for this? Seeking for anyone who experienced this before and manage to get it work smoothly. Plugins is working though except for the redirection after changing password.
